INTRODUCTION
FEATURES
Chapter 2. Installation and Operation
The MCP73837/8 AC/USB Dual Input Battery Charger Evaluation Board demonstrates
Microchip's stand-alone Linear Li-Ion Battery Chargers - MCP73837 and MCP73838.
The MCP73837 device features a Power-Good Monitor while the MCP73838 device
uses the same pin for the Timer-Enable function.
The MCP73837/8 require only minimum components to implement a complete battery
charge management circuit. The MCP73837/8 are designed to select AC-Adapter or
USB-Port Power Source automatically where AC-Adapter provides the charge current
when both sources are present.
The MCP73837/8 AC/USB Dual Input Battery Charger Evaluation Board comes with a
10-pin DFN MCP73837 and a 10-pin MSOP MCP73838 pre-installed. The different
packages can be easily evaluated by replacing the device, a resistor and a LED where
the patterns have been pre-designed on the board layout.
Typical applications for the MCP73837/8 devices are Smart Phones, PDA, Portable
Media Players, MP3 Players, USB-Powered Systems, Digital Cameras, Handheld
Medical Instruments, Handheld Devices, Battery Chargers, Bluetooth headsets,
Ultra-Mobile PC and Portable Communicators.
The MCP73837/8 AC/USB Dual Input Battery Charger Evaluation Board has the
following features:
• DFN-10 and MSOP-10 package patterns for either MCP73837 or MCP73838
• 1000 mA maximum charge current for AC-Adapter Input Power
• 100 mA (low) and 500 mA (high) for USB-Port Input Power
• V
• Two status LEDs to indicate charge status
• Additional LED to indicate Power-Good (PG) (Available only for MCP73837)
• Timer Enable (TE) Test Point to enable/disable safety timer
• 2-position Dip Switch for USB charge current control High and Low
• Available THERM pin on the board for temperature monitoring with a thermister
(Available only for MCP73838)
